TO) AIRPLANE Filed Oct. 28, 1929 2 Sheets-Sheet 2 31wentor Patented Oct.14, 1930 UNITED STATES PATENT oFFicE WILLIAM '1. WELCH, OLE NEW ORLEANS,LOUISIANA TOY AIRPLANE 1 The present invention relates to improvementsin toy airplanes and has for an object to provide an improved toyairplane of that type which is adapted to travel back and forward on astring, one end of which is secured to the wall or a fixed support andthe other end held in the hand of the operator.

Another object of the invention is to provide an improved toy airplaneso constructed as to assume a position of delicate balance and stabilityon the string with means to avoid the bobbing up and down ofthe airplanewhich action would interfere with the speed of the same.

A further object of the invention resides in providing an improved toyairplane in which an improved wing structure is had providing therefromthe supports for the landing wheels, suspension pulley and string guide.

A still further object of the invention is to provide an improvedairplane in which a modification of the rudder construction is involvedto form a stabilizing eye for engaging the supporting string.

With the foregoing and other objects in view, the invention will be morefully described hereinafter and will be more particularly pointed out inthe claims appended 80 hereto.

In the drawings, wherein like symbols refer to like or correspondingparts throughout the several views Figure l is a perspective view of animproved toy airplane constructed in accordance with the presentinvention.

Figure 2 is a top plan view of the same.

Figure 3 is a side elevation.

Figure 4 is a front View.

Figure 5 is a side view with parts broken away and parts shown insection, and

Figure 6 is a transverse sectional view of the improved airplane. v

Referring more particularly to the drawings, 10 designates a body orcore in the nature of a fuselage. This body may be of any suitablematerial and has at its forward nose 11 a rotary propeller 12.

The rear portion of the body 10 carries the rudder mechanism 13 which ispreferably made from sheet metal. An eye 14 is also preferably stampedfrom the sheet metal of the rudder mechanism and twisted atsubstantially right angles as designated at 15 whereby the axis of theeye will lie parallel with the axis of the body of the airplane toreceive freely therethrongh the supporting string 16, one end of whichmay be aiiixed to a wall or some other stationary support, while theopposite free end is held in the hand of the operator.

This string 16 also passes beneath a grooved pulley 17 located at thecenter of balance of the airplane'and journaled on a shaft 18 mounted inupstanding bearing arms 19 that are preferably stamped from the uppermetal plane or wing 20. Cut out portions 21 are shown to be the resultof the stamping out of the upstanding supporting arms 19, these armsbeing bent upwardly from the plane of the wing 20. A string guide 22 isalso stamped out from the material of the wing 20 as shown by the outout portions 2-3 which overlies the body 10, so that the body reinforcesand strengthens the wing structure at a point where this cut out portion23 occurs.

The string guide 22 is formed with an elongated slot 24 for receivingtherethrough the string 16. The guide 22 is areferably curred to conformsomewhat to the curvature of the grooved periphery of the pulieyl'? butis spaced from said pulley and acts to prevent the string from leavingthe groove of the pulley and from getting between the sides of thepulley and the supportin arms 19 where such string would jam and becomedificult of disentanglement. I

The lower plane is shown. at 25 and is pref erably formed in one piecewith the upper plane 20, being connected therewith by a central web 26which is formed with an opening 2'? to receive the body 10 of theairplane. there being ample portions of the web 26 surrounding the body10 to reinforce and strengthen both wings. Also there are pref erablystruts or braces 28 between the upper and lower wings 20 and. 25outwardly of the web 26 to serves to maintain the proper reia-' tionshipand distance between the two pianes.
